What is the meaning of Inuyasha's background music "Thinking of Poetry" and what does it have to do with the plot?

Poetry is a style, similar to poetry.

Miss Tan's poem is probably a poem of missing. Ge Wei misses Inuyasha; Platycodon grandiflorum misses Inuyasha; Coral misses amber; These plots, this pure music, have appeared in different versions. . Personally, I think it's loud.
